New Fabrication Technique Allows More Control Over Electrical Properties
With increasing scientific and medical interest in communication with the nervous system, demand is growing for biomedical devices that can better record and stimulate the nervous system, as well as deliver drugs and biomolecules in precise dosages.
Tianfu Wu used to dream of the day when cancer could be detected long before it was diagnosed. Now he sees that day dawning because of a system his research group created called the ultrasensitive polymeric sensing system (UPSS), which may detect biomarkers early – well before an illness strikes.
A UH biomedical engineer is zeroing in on the gap where nerve meets muscle to bring more precise treatment to stroke patients. The National Institutes of Health (NIH) awarded more than $434,000 to Assistant Professor Yingchun Zhang to delve deep into the neuromuscular junction, the connector of the nerve and muscle fiber, to calculate the exact spot to deliver the dose of motion-restoring Botox.
Every two seconds someone in the United States needs blood, according to America’s Blood Centers, generating a fundamental need to keep the blood supply healthy. A significant part of that process is to remove the white cells (leukocytes) from donated blood.
Cullen College’s biomedical engineering department was host to Houston’s Turkish consul general on Nov. 1. Ferhat Alkan met professors and visited labs before having lunch with a few faculty and staff members.
If it has to do with the brain, Associate Professor of biomedical engineering Joe Francis’ neurons are crackling. While he continues teaching robots to sense what humans want through brain research, he’s just published a paper in the Journal of Neural Engineering where he shares his ideas to restore the lost sense of touch by electrical stimulation of the central nervous system.
Biomedical engineers at the UH Cullen College of Engineering have identified several new blood biomarkers that can help to predict which lupus patients will progress towards more severe forms of the disease.
A biomedical engineer at the University of Houston is developing new techniques to map the structural integrity of the human cornea, work that could lead to more effective therapies for degenerative corneal disease.
Joseph T. Francis, associate professor of biomedical engineering, has earned four grants amounting to more than $4 million since he joined the faculty at the UH Cullen College of Engineering less than six months ago.
Maternal exposures to alcohol and nicotine, which are sometimes abused during pregnancies, are linked to fetal growth retardation and neurotoxicity. However, the individual and combined effects of the toxins on molecular mechanisms of fetal development are poorly understood.
Two professors at the UH Cullen College of Engineering earned a $200,000 Peer Reviewed Medical Research Program (PRMRP) Discovery Award from the U.S. Department of Defense to further explore a quantitative assessment technique for systemic sclerosis (SSc). The autoimmune disorder is characterized by thickening of soft tissues in the body caused by accumulations of collagen.
Lupus is an autoimmune disease that affects approximately 1.5 million Americans, according to the Lupus Foundation of America. In lupus patients, antibodies that are produced by the immune system’s B cells to protect the body against invading bacteria and viruses also attack the body’s healthy cells.
Lupus is a chronic autoimmune disease without a cure and without a highly effective treatment option. Many scientists believe that genetics and environmental factors interact to cause immune cells in the human body to overreact and attack healthy cells and organs in the estimated 1.5 million Americans affected by the disease.
An estimated 1.5 million Americans and at least five million people worldwide live with a form of lupus, a chronic autoimmune disorder, and approximately 16,000 new cases are diagnosed in the United States each year, according to the Lupus Foundation of America website. Almost 90 percent of those diagnosed with the disease are women between the ages of 15 and 44.
